This makes me wonder if it's worth considering a compartment that preserves
cold air. Imagine sucking the cold air into a second volume and leaving
(rather forcing) a vacuum inside the body of the fridge. Then the fridge
can be opened (*sarcasm* dead hard because of the vacuum), closed again.
The air is then sucked out of the fridge to get vacuum again. The cold air
can then be returned into the fridge. Then again, that suction takes up
plenty of energy...
